Description

图像形成设备和图像形成系统 The image forming apparatus and an image forming system

技术领域 FIELD

[0001] 本发明涉及诸如复印机或打印机等能够进行调整操作的图像形成设备以及包括相互连接的多个这类图像形成设备的图像形成系统。 Relates to an image such as a copier or printer adjustment operation can be performed [0001] The present invention is such an image forming apparatus and includes a plurality of interconnected devices forming an image forming system.

背景技术 Background technique

[0002] 作为传统的图像形成系统,已知有如下的系统:在该系统中,将在记录纸的正面形成图像的第一图像形成设备与在该记录纸的背面形成图像的第二图像形成设备连接在一起以在该记录纸的两面上都形成图像(例如,参见日本特开2004-268572)。 [0002] As a conventional image forming system, there is known a system: In this system, forming a first image and the second image forming apparatus forming an image on the back surface of the recording paper on the front side of the recording sheet device connected to an image is formed (e.g., see Japanese Patent Laid-open 2004-268572) on both sides of the recording paper.

[0003] 更具体地,在由第二图像形成设备在记录纸的背面形成图像之前,将由第一图像形成设备在其正面形成了图像的记录纸反转并输送至第二图像形成设备。 [0003] More specifically, prior to the second image formed by the image forming apparatus on the back of the recording paper by the first image forming apparatus is formed in the front side thereof an image recording sheet is reversed and conveyed to the second image forming apparatus.

[0004] 一些图像形成设备进行诸如灰度校正等的调整操作以使输出至记录纸的图像的图像质量稳定。 [0004] Some image forming apparatus such as a gradation correction operation or the like to adjust the output to stabilize the image quality of the image recording paper. 例如,一些图像形成设备在中间转印带上形成灰度校正用的图案图像,以基于通过读取该图案图像所获得的数据进行灰度校正(例如,参见日本特开平6-148992)。 For example, some image forming apparatus are formed on the intermediate transfer belt used in gradation correction pattern image, based on the pattern image data by reading the gradation correction is obtained (e.g., see Japanese Patent Laid-Open 6-148992).

[0005] 然而,如果要在根据日本特开2004-268572的图像形成设备中进行根据日本特开平6-148992的调整操作,则需要在第一图像形成设备和第二图像形成设备各自的调整时刻处进行调整操作。 [0005] If, however, to be formed according to JP 2004-268572 image apparatus according to Japanese Unexamined Patent Application 6-148992 adjustment operation, the adjustment time is necessary to form the respective image forming apparatus and a second apparatus in the first image the adjustment operation.

[0006] 如图7的具体例子所示,将示出在总共21个时间段内对第一图像形成设备设置6个调整时刻并且对第二图像形成设备设置5个调整时刻的例子。 [0006] Specific examples as shown in FIG. 7, will be shown in a total of 21 periods of the first image forming apparatus 6 is provided to adjust the time and examples of apparatus 5 is provided the time to adjust the second image forming. 在这种情况下,当图像形成系统被认为是整体时,如果图像形成设备的其中之一进行调整操作,则无法进行作为图像形成系统的操作。 In this case, when the image forming system is considered to be a whole, if one of the image forming apparatus performs adjustment operation can not be performed as the operation of the image forming system. 因此,图像形成系统停止图像形成操作,由此在整体系统中引起10个停止时间段。 Accordingly, the image forming system stops an image forming operation, thereby causing 10 stop periods in the entire system.

[0007] 因此,在连接多个图像形成设备的传统图像形成系统中,在图像形成设备各自的调整时刻使整体系统中的图像形成操作停止。 [0007] Thus, in the conventional image forming system connected to a plurality of image forming apparatus, the image forming apparatus to adjust the timing of each image forming operation of the entire system is stopped. 因此,在传统图像形成系统中发生长的停机时间,由此导致生产率下降。 Thus, a long downtime occurs in the conventional image forming system, thereby resulting in decreased productivity.
